Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584284, here are decompositions:

3 + 31584281 = 31584284
37 + 31584247 = 31584284
73 + 31584211 = 31584284
241 + 31584043 = 31584284
313 + 31583971 = 31584284
373 + 31583911 = 31584284
421 + 31583863 = 31584284
643 + 31583641 = 31584284

Showing the first eight; more decompositions exist.
